I have a .50 caliber TC Hawken that I have owned for years. When I bought the rifle, it came with several additional items which included a box of Buffalo Bullet ballettes. I finally decided to try them and and when I did I found them difficult to start with a short starter. After I gave one a whack with a small plastic mallet I was able to finish with the short starter and then seat it with the ram rod. I tried a couple more but I decided to stop because the plastic hammer was deforming the nose of the ballettes. The ballettes measure .505" and they are prelubed. Does anyone have suggestions?
